Comparison of laparoscopic percutaneous extraperitoneal closure and laparoscopic intracorporeal suture in pediatric hernia repair

BackgroundLaparoscopic inguinal repair use is rapidly growing because it is a minimally invasive surgery (MIS) technique. However, there is insufficient evidence to support the use of one MIS over others. We compared laparoscopic intracorporeal suture (LIS) and laparoscopic percutaneous extraperitoneal closure (LPEC) to determine which technique is superior.MethodsBetween February 2017 and December 2019, 260 children who underwent LPEC and 214 children who underwent LIS were enrolled. Operative time, recovery score, and patient cosmetic satisfaction were compared. A total of 108 propensity score-matched pairs were analyzed using paired t-test for continuous measurements and McNemar test for categorical variables.ResultsThe mean surgery time was lower in the LPEC group for both unilateral (15.76 ± 5.35 vs. 19 ± 5.71 min; p = 0.04) and bilateral (21.56 ± 5.7 vs. 26.38 ± 6.94 min; p = 0.01) surgeries. The LPEC group required shorter time for complete recovery (p = 0.017). The mean rating for scar visibility was higher in the LIS group (p = 0.02); however, both groups had high levels of cosmetic satisfaction (p = 0.125).ConclusionLPEC for hernia repair is safe and efficient in children and reduced operative time, hastened recovery, and provided excellent cosmetic results.
